Fix binary diff showing /dev/null

Fix #5565

Pre-Android 5 did not implement a virtual filesystem atop FAT partitions for Unix permissions, which causes chmod to fail. However, Unix permissions have no effect on Android anyway as file permissions are not actually managed this way, so treating it as a no-op across all Android is safe.

When trying to the template dir, we pass in a `NULL` pointer for the
filename. That's perfectly fine, but if we're failing to find the
template directory then we'll creat an error message with the `NULL`
pointer passed in.

Fix the issue by setting different error messages based on whether the
filename is given or not. This even makes sense, as we're not searching
for a file in case we have no `name`, but for a directory. So the error
would've been misleading anyway.

Fix deprecation links inside of documentation not working

When building libgit2 with the release build type, then GCC complains
about mode being potentially uninitialized. While this seems to be a
false positive, let's silence this warning by zero-initializing the
mode.

The `signature` variable in `git_reference_rename` isn't initialized and
neither does `git_reference__log_signature` always do. So if the latter
function fails, we'll call `git_signature_free` on this unininitialized
variable.

Fix the issue by initializing the pointer with `NULL`.

Don't fail if a HTTP server announces he supports a protocol upgrade

cf. RFC7230 section 6.7, an Upgrade header in a normal response merely informs the client that the server supports upgrading to other protocols, and the client can ask for such an upgrade in a later request. The server requiring an upgrade is via the 426 Upgrade Required response code, not the mere presence of the Upgrade response header.

(closes issue #5573)

Return false instead of segfaulting when checking for default port

`default_port_for_scheme` returns NULL if the scheme is not one of the
builtin ones. This may cause a segmentation fault if a custom transport
URL happens to contain a port number, and this code path is triggered
(e.g. by setting git_fetch_options->update_fetchhead to 1).

azure: Remove job generating documentation

This follows up on 11de594f which added
support for parsing patches without extended headers (the "index
<hash>..<hash> <mode>" line); issue #5267.

We now allow transition from "file mode" state to "path" state directly
if there is no "index", which will happen for patches adding or deleting
files as demonstrated in added test case.

Fix crash in git_describe_commit when opts are NULL.

The argument "opts" can be NULL, which selects default options. Do not access
"opts" directly but only the normalized copy.

With the recent addition of GitHub Actions to our CI infrastructure, we
now have two jobs which generate documentation: once in GHA, once in
Azure. Naturally, as they both want to update the same branch, they race
against each other and one of both jobs will fail.

Fix this by removing the documentation job from Azure.
